APPLICATION INFORMATION (continued)
Figure 14. Three Wire Interface
Notes on SPI and Microwire: Before the controller starts the data transfer, the software has to generate a falling
edge on the I/O pin connected to FS. If the word width is 8 bits (SPI and Microwire), two write operations must be
performed to program the TLV5636. After the write operation(s), the DAC output is updated automatically on the
next positive clock edge following the sixteenth falling clock edge.
The maximum serial clock frequency is given by:
The maximum update rate is:
Note that the maximum update rate is just a theoretical value for the serial interface, as the settling time of the
TLV5636 has to be considered, too.
The 16-bit data word for the TLV5636 consists of two parts:
